Re: Windshield washer (fluid)
I don't seem to have a problem with chattering from my wipers. I don't think, even with chattering, that this would cause noticeable or accelerated wear to your wipers. Typical wiper life is 6-12 months. I am fortunate that mine have lasted 18 months with no degradation noted. It is also really dependent on the solution your are using, if you use the bug removing washer fluids, this stuff will attack the rubber on your wipers and will substantially reduce the wiper life. I stick with the good old blue methanol based washer fluid in the summer and the prestone antifreeze washer fluid in the winter. Good Luck.
